In the drawings, V-105 -indicates the main ybody Vof a'drum and;11`,111 indicates the j heads thereof, the edges of said heads being engaged, in" the usual A"manner, kby y the head 1 rings 12, 12whichk embrace the main bodyA 10. These rings may be of sufficient"v width yto receivefmy improved tension devices but I prefer tofprovide an additional ring 13' i @to coperate with each ring 12, the ring 13 being formed of light angle iron having a horizontal inwardly` projecting flange adapted to overlie the adjacent head ring.

12. Thus far thev construction is substanwith lthe, yielding pressure of the spring 21 so that, as the skins 11 tend to loosen or tighten `nnd'er varying 'weather conditions', the springs21 will permit a yield of the ringsfl axially "of the main body of the drum to compensate for-the change in con-v dition of the skins.

Indo-rden tomake a sightly'.c'onstructi oni onewhich can be readily. applied to-existingdruinsgand which canbe easily handledL Awithout; having its parts become sepa,`

rated, I prefer to employ a plurality .of .parkticular .spring: constructions'shown in, def y ,Y y A tall m`gF1g..3, the various parts of which can .lfhe obj'ectgof'my invention'ls'to .producev bez-readily yproducedat minimumcost and "ea'sily.;assembled.y j this preferred formk oftenslon device I .provide two similar;

heads 25, 25 each of which is axiallythread-` ed andprovidedon its outer endwith an anable openings in the horizontal: fl'angesof the rings 13, .the screwV 28being conven-.. iently provided with a -knurled head y29 by means of which it may-be readily turned so` i i the spring 21. Two.diametricallylopposite as, to adjust .the tensionof-the spring 21;` The barrel ofthe tension device'is composed of foursheet metal segments 30 which'are. vpressed intocylindrical segments .and have their ends turned inwardlyyto form seg-j mental .hooks whichl` may i' either f take over I the ribs 26 of heads 25 or over'the coilsfof 80- segmentsBO are then hookedover the-rib 2 6 r .of one head and overtheopposite'endof spring-21,2while the other two segmentsBOl are hooked overthe rib 26 of the other head and overthe v'opposite end 4of 'spring 21, this? last operation beingaccomplished-by first compressing the spring slightlyv so that when the parts are released each head 25 will be held againstthe adjacent end ofthe spring and thespringwill be under slightk compression, `thus holding'the parts firmly in placelso that the article maybe readily handledand shifted without becoming dismembered. j l 4 yIn order that the snare`s"40 may have a uniform effect 'on the drum head they are l Amounted in brackets secured vto the body of the drum instead of tothe head rings and in Fig. 2 I show oneof these brackets;y

41 as a support for a-kscrewg42 ,whichpasses freely through the bracketand is threaded into the cross bar 40 of the snares. Be-

ftween the head of screw 42 and thebracket 41 I arrangey a `spring k43k the tension of v which may be adjusted 'by anadjustment of n v of. said lmeinbers'fy'eng-'agn'g the spring,
